` tion of the same.

. invention in whatever The invention relates more particularly to a support mounting for frictionally controlling the operation of tilting sashes.

Among the objects of the invention are to provide a mounting that will hold the sash at any desired inclination and of such construction that'it may be easily applied to the window structure.

In this specification and the annexed drawing is illustrated the invention in the form that is considered to be the best but it is to be understood that said invention is not limited to such form because -the same may be embodied in other forms, and it is also to be understood that in and by the claims following the description it is desired to cover the form it may be embodied.

In the accompanying drawings Figure 1 is a perspective view of a window easement having sashes mounted therein in accordance with this invention, the view being taken from the outside of the window.V

tional view thereof.

This invention with slight modifications is adaptable to the various lnds of window easements and sashes at present in use.

In detail, the construction illustrated in the drawings includes a easement 'comprising a sill 1, the side jambs 2, 2 and the lintel 3. This main frame is provided with the exterior trim 4' and the interior stops 5 and 6 and the stool 7 The window opening thus vswings on the pivot 13, slidable in the sleeve 14, Xed in the sash. The sash pivot 1s provided with the shoe 15, pivoted thereon and embracing and bearing against the shoe 12, against which it is forced by the tension of the spring 16, inclosed within the sleeve 14, behind the pivot 13. The sliding of the pivot .shoe 15, on the shoe 12 is controlled by the control arm 17 pivoted at 18, to the slide 12, and at 19 `to the side of' the sash. The weight of the sash is supported by the arm 20, pivoted at 21 to the window easing and at 22 to the side of the sashes, the pivots 22 acting as the fulcrum upon which the sash moves in assuming the various angles of inclination to which it may be adjusted by the operator. The various mechanisms above described are duplicated upon opposite sides of the window opening and the sashes, each sash within 'the easement being similarly mounted, and one detailed description is therefore deemed sufficient.

The sashy is operated substantially as follows When the bottom of either sash is pushed outwardly, as illustrated in Figs. 1 and 4, the support arms 20 assume a proportionate angle, thepivots 22 causing the upper rail of the sash to slide downwardly, the arms 17 causing the shoes 12 to slide on the guides or tracks, with the retard caused by the friction between the shoe 12 and the guide induced by the expansion of the spring 16, be-4 Assren'on. 'ro smarter.4 WINDOW complementa] bosses 24, as illustrated in` outwardly, because ofthe greater leverage in favor of the operator. On the other hand such natural forces as Wind, and gravitation, acting as they do on the Whole glazed surface of the sash, are equalized by the position of the4 pivots 22, and by the resistance of the smaller toggles which are locked in position by the friction of the shoes 15 on the shoes 12, and these in turn exert a binding friction on the guides or rails 10, effectually holding the sash against the action of the elements at any desired angle. This arrangement of levers and supports and the application of friction in the manner described, provides meansfor e'ectively;

holdingH -the-v sash .in

come by the operator who has a greater leverage in his favor'. If it is desired to increase the friction between shoe l5 and the shoe 12, said shoes may be provided with Fig. 5.

Attention is directed to the fact that the whole mounting mechanism may be assembled upon the sash ready for installation` Within the window easement by merely attaching the guides or tracks 10 and 1l to the side jambs of the Casement. This is best illustrated in the upper sash in Fig. 1, in which the pivots 21 are attached to the track 11. The same construction could be carried out with regard tothe lower sash if desired.

This mounting is similar in every way to the-upper one with the exception that the pivots 21 are placed directlyv on the jambs of the casing, it being unnecessary to extend the track the full depth of the window opening. The sashes are completely reversible within the window opening by moving them into the positions shown in Fig. 1, and then moving the upper rail of each sash downwardly to the limit of its movement, as illustrated in Fig. 4. As illustrated in Fig. 1 the meeting rails of the sashes overlap as in common in the slide type of window. It is obvious, however, that the two sashes may hang in vertical alinement, the upper rail of the lower sash engaging into the under side of the lower rail of the upper sash. In lieu of providing ides 10 and 11 of the form illustrated 1n igs. 1,2 and 3, the same l any desired position,l such resistance however,"be1ng.eas1ly over-- may be made in the form of grooved members 25, and the shoes 26 and 27, connected with the sash and the arms 1 7, respectively, shaped to enter the same, See Figs. 6and 7 Having thus described this invention, I claim z* 1. A window mounting comprisin a casement provided .with guides, slide s oes engaging said guides, a sash, pivot shoes movably connected with said sash and slidable upon said slide shoes, and arms movably connected with said slide shoes and with said sash.

2. A window mounting comprising a casement provided with guides,slide ,shoes engagmg said guides, asash, pivot shoesnieve.

ablyconnect'ed witlf'said sash and slidable upon said slide shoes, arms movably connected with said slide shoes and with said sash, and support 'arms movably connected with said sash and with said easement.

3. A window mounting comprising a case-` ment, having shoe guiding means, shde shoes movably engaging said guiding means, a sash, pivot shoes movably connected with said sash and guided by said slide shoes, and arms movably connected with said slide shoes and with said sash. 4. A window mounting comprising a cascment having shoe guiding means, slide shoes movably engaging said guiding means, t sash, spring pressed pivot shoes movably connected to said sash near the upper corners thereof, and guided by said slide shoes, and arms movablyconnected with said slide shoes and with said sash.

5. A Window mounting comprising a casement having shoe guiding means, slide shoes movably engaging said guiding means, a sash, spring pressed pivot shoes movabl y connected to said sash near the upper corners thereof and guided by said slide shoes, arms movably connected with said slide shoe and with said sash, and support arms pivoted to the edge of said sash near the middle thereof, and to said easement near the position assumed by the lower end of the sash when in closed position.

In testimony whereof, I have hereunto set my hand at Washington, D. C., this 8th day of August, 1916.
